Preventing Soil Erosion. Agrotechnical and Agricultural Treatments for Land Protection



Intensive, long-term exploitation of arable land has led to many farms struggling with decreasing harvests. Less fertile soil results in lower yields. Farmers' initial response to declining yields was increased cultivation, deep plowing, fertilization, and plant protection products. However, this did not improve soil fertility or yields in the long term. It provided a temporary solution but ultimately resulted in further land degradation in subsequent seasons. This led to even more intensive agrotechnical treatments and higher usage of chemicals on crops, which is detrimental to the soil, crops, environment, and consumers. It is also uneconomical due to rising costs of fuel and agricultural chemicals. It is not ecological. Caring for the soil is now fundamental to agriculture, and the understanding that cultivation depends on fertile land is the foundation for many agrotechnical treatments. Rolmako supports this approach by offering machines designed for no-plough and ultra-shallow cultivation.

How to Prevent Soil Erosion: Conservation Approach in Agriculture



The conservation tillage system is an agricultural method that reduces the need for energy and labor while minimizing machinery maintenance costs. This effective solution contributes to increasing the durability of soil aggregates and the intensive development of biological life, especially the earthworm population.

Limitation of agrotechnical procedures



The absence of soil turning and mixing in conservation systems reduces water losses and increases the durability of soil aggregates. Consequently, the topsoil layer becomes richer in humus, and the leaching of nutrients into the ground slows down. Reducing the number of agrotechnical treatments enhances soil moisture retention and reduces drainage, thereby improving water absorption deep into the soil profile.

Reduction of soil erosion



The conservation tillage system effectively prevents soil erosion, particularly in hilly areas, by leaving crop residues on the field surface. Consequently, the land is protected against wind and water erosion, improving its structure and porosity and increasing biological activity, including the population of earthworms.

Use of optimal tools



In conservation tillage, it is crucial to employ appropriate tools, such as direct drills, which minimize soil disturbance and enable precise seed placement. It is also essential to use loosening elements before sowing, ensuring proper contact of the seeds with moist soil, thereby promoting their germination and plant growth.


Using optimal farm equipment for direct seeding and loosening soil




Rolmako's range includes modern agricultural machines designed for no-plough and ultra-shallow cultivation. The lack of interference in the deep soil layers, combined with mixing organic residues and mulching, serves as an agrotechnical method to prevent soil erosion, restore fertility, and improve structure. Periodically, it is advisable to loosen the soil with suitable equipment. A subsoiler with well-chosen tines disturbs the deeper soil layers, thereby breaking up the structure beneath the typical cultivation depth. To maintain soil condition, this treatment is performed every few seasons. Rolmako's wide selection of subsoilers allows you to precisely match the equipment to your needs.

Challenges and Compromises



Despite its numerous advantages, the conservation tillage system has drawbacks. There is a risk of increased diseases, weeds, and pests, as well as the possibility of topsoil acidification. It is also important to adapt agricultural machinery properly and consider the possibility of using plowing technology under unfavorable conditions for direct sowing.

Consequently, conservation tillage is an effective method for enhancing soil fertility and preventing erosion, thereby contributing to sustainable agricultural development and environmental protection. However, for optimal results, appropriate practices and tools must be utilized, considering both the benefits and challenges of this approach.

A compromise between preventing soil erosion and cultivation using a plow



Strip cultivation—also known as strip-till—combines traditional agricultural methods with a modern approach to soil cultivation. A strip of land is loosened, leaving the soil layer intact. This system creates optimal conditions for plants while minimizing water losses. However, it reduces the cultivation area and complicates compliance with the principles of the European Green Deal, offering both advantages and disadvantages.


Strip tillage as a compromise between traditional cultivation and soil protection




Strip tillage gained popularity in the 1990s in countries such as the USA, Canada, and Australia. Originally conducted in two stages, it now utilizes a single-stage process where a strip of soil is loosened and seeds are sown. It combines the benefits of plow cultivation and direct sowing, providing optimal conditions for plant growth. Intact strips of soil remain microbiologically rich and abundant in earthworms beneficial to plants.

Soil protection against erosion: mulching, forecrops and cover crops, crop rotation



Beyond agrotechnical measures, effective management of soil resources is crucial. Mulching stands out as the optimal approach, best facilitated by utilizing specialized machines from the Rolmako range. Leaving organic matter on fields during non-cultivation periods safeguards the soil against moisture depletion, wind erosion, and nutrient loss.

Cover crops and aftercrops adapted to the type of soil enrich the land. Many plants not only create a protective layer but also bind minerals in their roots. This is why nitrogen-fixing legumes are commonly used as cover crops. Furthermore, the roots of cover crops effectively enhance the structure and oxygenation of the soil.

An important aspect of preventing soil erosion is also conscious cultivation and the use of crop rotation, known for centuries. The variability of crops has not become outdated; on the contrary, scientific research confirms that it is a practice that has a very beneficial effect on the soil.

Caring for soil as a priority in modern agriculture



Preventing soil erosion and improving crop yields in an environmentally friendly manner is now a priority. Agricultural machinery manufacturers, such as Rolmako, are adapting their offerings to current requirements and soil-conserving cultivation methods. Scientists are seeking natural ways to enrich the soil with nitrogen or to protect against wind and water loss. The latest trends in crop cultivation will eventually translate into healthier agricultural products, economical and ecological farming, reduced chemical threats, and a reduced carbon footprint.
